WordPress + bbPress 1.1 both in web root

I’ve got them both in the root at the moment and playing nice as far as integration goes, but not as far as the permalinks work. I can’t have both working at the same time, one works or the other doesn’t.

I want my URL structure to operate as follows

bbpress – /forums/ – /profiles/ – /topic/ etc

Wordpress – /category/ – /archives/ – /sample-page/

Is this possible? Or is it possible if I put one of them in a sub folder…
